Privacy Policy

1) Information We Collect

Most calculator inputs are processed locally in your browser for standard use. We do not require account creation to access core calculator features. We may collect limited technical information such as browser type, device type, referrer, country-level location, and basic server logs to maintain performance, security, and service quality.

2) How We Use Information

We use information to operate calculators, improve user experience, troubleshoot technical issues, prevent abuse, and measure product performance. We may also use aggregated, non-personal usage insights to improve site content and feature quality.

3) Cookies and Similar Technologies

We and our partners may use cookies or similar technologies for essential site functionality, analytics, personalization, and advertising. You can control cookies in your browser settings. Disabling certain cookies may affect parts of site functionality.

4) Google AdSense and Advertising

We may display ads served by Google AdSense and other advertising partners. These providers may use cookies to serve ads based on your prior visits to this and other websites. Google's advertising cookies help deliver more relevant ads and support publisher monetization.

Users may opt out of personalized advertising by visiting Google Ads Settings. You can also visit aboutads.info for more information about interest-based advertising controls.

5) Third-Party Services

Our website may include third-party tools, analytics, embeds, or links. These services may process data under their own privacy policies. We recommend reviewing third-party privacy terms before using their services.

6) Data Retention and Security

We retain only the minimum information necessary for operations, security, legal obligations, and service improvement. We use reasonable technical and organizational safeguards to protect information, but no internet transmission or storage system can be guaranteed 100% secure.

7) Children's Privacy

Our website is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal data, please contact us so we can review and remove it where appropriate.

8) Your Rights and Choices

Depending on your region, you may have rights to request access, correction, deletion, or restriction of personal data, and to object to certain processing. You may also manage cookie preferences through browser controls and available consent tools.
